In the event that production, operations or activities cannot be curtailed so as to so limitthe total aggregate emissions without jeopardizing equipment or safety or measures taken would result in even greater excess emissions, the owneroroperator ofthe source shall usethe most rapid, reasonable procedure to reduce emissions. The owner or operator ofany installation subject to a SIP emission limitation pursuantto these rules shall be deemed to have complied with the provisions of R307­ 107 ifthe emission limitation has not been exceeded.
